Neutral grasslands

Context

Neutral grassland is characterised by vegetation dominated by
grasses and herbs on a range of circumneutral soils. It
includes dry hay meadows and pastures, together with a range of
grasslands which are periodically inundated with water or
permanently moist. Most of these habitats occur below the
level of agriculture enclosure, and are thus considered
'lowlands'.

Neutral grasslands are sometimes referred to as mesotrophic
grasslands. For the most part, neutral grassland communities
have few diagnostic indicator species but lack strong calcicoles or
calcifuges characteristic of base-rich and acid soils
respectively. Unimproved or species-rich neutral grasslands
are usually managed traditionally as hay-meadows and pastures:
species present include a variety of flowering plants, such as
snake's-head Fritillaria meleagris, dyer`s greenweed
Genista tinctoria, green-winged orchid Orchis
morio, greater butterfly orchid Platanthera
chlorantha, pepper saxifrage Silaum silaus and wood
bitter vetch Vicia orobus.

Natura 2000 comprises Special Protection Areas (under the Birds Directive) and Special Areas for Conservation (under the Habitats and Species Directive). The list presented here includes all of the qualifying interest features under these Directives, and shows the proportion of these features for which a condition assessment has been made.

Maps - distribution

Distribution of reported interest features.

Map showing the locations of the 10km squares in which at least one condition assessment has been reported. It does not show features that have not yet been assessed.

Maps - Natura

Current condition of SAC features
Distribution of SAC features showing assessments of favourability (where unfavourable-recovering is counted as unfavourable).

Condition of SAC features, with those currently reported as unfavourable-recovering shown as favourable
The implication of the unfavourable-recovering condition assessments is that at some point in the future these features should become favourable. This map shows the effect of that recovery by counting the favourable and unfavourable-recovering assessments together.

IMPORTANT NOTE: we do not have information on the timescale of the predicted recovery, which may be influenced by many past, natural and human related factors. A sustained sympathetic management regime is more likely to result in favourable condition being attained.

Condition summary

This lists the 10 different condition assessments and presents a bar chart showing the number of features within the SSSI series and the Natura 2000 series (either SPA for bird features or SAC for features other than birds). Note that for Natura 2000 we are able to estimate the number of features that have not been assessed during the 6 year reporting period - we are unable to do this for SSSI/ASSI because we do not have an overall list of notified interest features for these designations.

NB favourable unclassified and unfavourable unclassified have been used in this first six year cycle to get around difficulties in identifying trends in condition as common standards monitoring is implemented. It is expected that these categories will not be used for subsequent assessments of a feature.

Condition assessment - Natura 2000 features

The number and proportion of assessments for Natura 2000 (SAC and SPA) interest features falling into each of the condition categories. Note that the �unfavourable� category includes all reports of unfavourable condition except �unfavourable recovering� which is shown as a separate segment.

Condition assessment - SSSI features

The number and proportion of assessments for SSSI/ASSI interest features falling into each of the condition categories. Note that the �unfavourable� category includes all reports of unfavourable condition except �unfavourable recovering� which is shown as a separate segment.

Adverse activities

The number of interest features where an activity has been reported as being implicated in the "unfavourable" condition of a feature. More than one adverse activity may be reported for each feature.

Management measures

For each "measure" the chart shows the number of interest features where that measure has been taken on a site to improve or maintain the condition of an interest feature. More than one measure may be reported for each feature assessed.

Interpretation

42% of neutral grassland features reported are in favourable
condition. This is just above the average for terrestrial
habitats, about the average for all habitats and below the average
for all features combined. 42% of A/SSSI features and 38% of
SACs reported are in favourable condition.

The unfavourable-recovering category accounts for about a
quarter of features reported (26% of A/SSSI and 25% of SAC
features). Thus many sites, although currently unfavourable,
have management plans in place to promote a return to favourable
condition. Although there are initiatives in place to promote
recovery of feature condition, more restoration management is
needed.

Under-grazing and abandonment are the main causes of
unfavourable condition. Scrub encroachment is the common
result, sometimes together with bracken and/or invasive species
problems. Additionally, some sites are also affected by
over-grazing and nutrient enrichment. Underlying causes of
under-management are still thought to be largely due to current
agricultural economics and policies, exacerbated by for example,
BSE and Foot & Mouth disease, leading to a reluctance to keep
stock (large stock in particular) on pasture perceived to have
little nutritional value. Nutrient-enrichment through
fertilizer application is still a concern, but is very difficult to
monitor. In addition, the extent to which atmospheric
nutrient deposition is affecting the composition of lowland neutral
grassland sites is a largely unknown quantity.
